HEATER FOR RAI LWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 340,258, dated April 20, 1886.

Application filed October 15, 1884. SerialNo. 145,607. (No model.)

To aZZ whom it may concern.-

Be it known that LGHARLES TURNER, a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Heaters for Railway-Oars, which are fully set forth in the following speci fication, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of a locomotive and that portion of my device which is attached thereto; Fig. 2, aside elevation of a car having my devices applied thereto, a portion of the side being broken away to show the construction; Fig. 3, a plan/section on the line :0 :0 of Fig. 1; Fig. 4, a plan section on theline y y of Fig. 2; Fig. 5, an enlarged View of a portion of the same; and Fig. 6, an enlarged elevation of the shield, portions of one side being broken away to show the interior.

Like letters refer to like parts in all the figures.

My invention relates to ventilating devices to be applied to railway-ears, its object being to furnish a full supply of fresh pure air free from smoke, cinders, and dust, the air so supplied being heated in cold weather; and to that end my invention cousistsin certain novel features, which I will now proceed to describe, and then particularly point out in the claims.

In the drawings, A represent-s a locomotive of ordinary construction,above the steam-chest a of which are attached funnels B, suitably connected to the forward end of the main airsupply pipe 0. By reason of this location of the funnels B a constant supply of airis forced into them by the motion of the train, and so through the pipe 0, from which it is distributed, as hereinafter described. Moreover, the mouth of the funnels being in advance of the smoke-stack, the smoke and cinders from the stack cannot enter,nor can the dust caused by the train, thereby insuring the purity of the air-supply. The air-supply pipe 0 is of iron or other suitable material, and a section of it is secured under each car 0, and also under the tender and to the locomotive, being shown in Fig. 1 as attached immediately under the foot-board b, so that it will be out of the way and protected from injury.

Suitable flexible connections are employed between the sections on the cars, tender, and locom0tive,as hereinafter doscribed. That section of the supply-pipe 0 attached to the locomotive is shown as in duplicate, one part being on each side and the two parts joining at the rear. The section of pipe 0 under each car Ois provided with a stop-cock, c, at each end,so that the rear end of the last section of pipe may be closed to prevent the air from passing straight out through the rear end of pipe 0 without entering the carat all. Near each end of the car the pipe 0 is provided with a branch pipe, D, entering the interior of the car, being shown in Fig. 2 as passing up through the floor and having a stop coek, d, by which the flow of air can be regulated or entirely stopped. If in cold weather the outer air were allowed direct access to the interior of the car, it would reduce the temperature too much. I overcome this difficulty as follows: In Figs. 2 and A E represents a stove or heater, such as usually employed in passenger-cars, there being either one at one end of the car only, or, as isniore usual, one at each end. E indicates asereen arranged between the carwvall and stove, to protect the former from thehcat. For use in conjunction with my apparatus, I make this screen, which is of sheet-iron or other suitable material, hollow, as shown in detail in Figs. 5 and'G, and arrangeinside of the same partitions 0, attached alternately to the top and bottom of the hollow screen and extending not quite all the distance from top to bottom. The branch-pipe D communicates with the interior of the shield at the side there of farthest from the car-door, and the air entel-ing through thebranch pipe passes through the interior of the screen in the manner indicated by the arrows in Fig. 6, and then out through the nozzle'or outlet-pipe F into the interior of the car. In its passage through the screen E the air becomes warmed to a proper temperature, so as not to chill the interior of the car, and at-the same time it reduces the temperature of the screen by absorbing its heat, thereby rendering it a more eflicient protection to the WOOd-WOI'K of the car. Owing to the position of the outlet-pipe F near the door, any cold air admitted by the necessary opening of the same will receive such an admixture of warm air as will raise its temperature as soon as it enters the car.

At the same I time the outlet-pipe is so located as to be as far as possible from any of the seats, so as not to expose the passengers to a disagreeable current of air. The outlet-pipe may be provided with a cock, f, to regulate the flow of air and the rate of its passage through the screen. Of course in warm weather, when the heater is not in use, the air may still pass through the screen, though of course without becoming heated. The sereen'in this case, as indeed in the other, deprives the air of any einders or the like which may accidentally have entered the pipe 0.

The various fixed sections of the pipe 0 are connected by flexible pipes. This is accomplished by attaching to each end of each section, except of course that attached to the locomotive, a flexible tube, G, ofrubber or other suitable material. In order to allow extra play I slip this tube over the end of pipe 0, and attach to it one end ofa spring, g, coiled around pipe 0, and having its other end attached thereto. By this means, when any strain comes upon the tube G, it will slide upon pipe G, and when the strain is removed the spring y will return it to its normal position.

From the above description the operation of my device will be readily understood.

It is obvious that many mechanical modifications in the construction maybe made witl1- out departing from the principle of my invention, and I therefore do not wish to be understood as limiting myself strictly to the precise details of construction shown and described.

Having thus described my inventiou,wl.iat I claim as new, and desire to secure by Letters Patent, is-

J. In a car-ventilator, the combination, with the funnels B,arranged as specified,of the pipe 0, having its several sections connected by fiexibletubing, and provided with branch pipe D, hollow screen E, connected therewith and having an outlet-pipe, and heater E, substantially as and for the purposes specified.

2. In a car-ventilator, the combination, with the main air-supply pipe (7, of hollow screen E, connected thereto by a branch pipe, D, and having an outlet-pipe, F, the said screen having the partitions e, extending alternately from the top and bottom almost to the opposite end of the screen, and heater E, substantially as and for the purposes specified.

3. In a car-ventilator, the combination, with car 0 and heater E ,arranged therein in one corner thereof, of hollow screen E, partly surrounding said heater and having a branch pipe, D, at the side thereof farthest from the eandoor,and com muuicating with the supplypipe 0, and an outlet-pipe, F, at the side nearest the car-door, substantiallyas and for the purposes specified.

4. In a car-ventilator, the combination, with supply-pipe (1, having a stop-cock, c, at each end of the car, of hollow screen E, branch pipe D, connecting the two and havinga st0pcock, (I, and outlet-pipe F, having stop-cockf, substantially as and for the purposes specified.

5. In a car-ventilator, the combination, with the locomotive A, of the funnels B, arranged as specified, and supply-pipe sections (Larranged immediately under the foot-boards b, substantially as and for the purposes set forth.
